15V745000 · Equipment:Recreational Vehicle/Trailer
Reported: 2015-11-10 (November 10, 2015)
Thor Motor Coach (Thor) is recalling certain model year 2011-2016 Thor Challenger, Thor Citation, Thor Hurricane, Thor Tuscany, Thor Windsport, 2011-2012 Thor Astoria, Thor Avanti, Thor Chateau, 2011-2014 Thor Daybreak, 2011-2015 Thor Outlaw, Thor Siesta, 2014-2015 Thor Miramar, 2012 Thor Four Winds, 2008-2011 Damon Astoria, Damon Daybreak, Damon Outlaw, Damon Tuscany, 2008-2012, Damon Challenger, 2008-2010 Damon Essence, 2009-2011 Damon Avanti, Four Winds Chateau, Four Winds Citation, Four Winds Four Winds, Four Winds Hurricane, Four Winds Siesta, Four Winds Windsport, 2009-2010 Four Winds Dorado, Four Winds Dutchmen, Four Winds Magellan, Four Winds Mandalay and 2009 Four Winds Fun Mover, and Four Winds Presidio motorhomes. The affected vehicles are equipped with certain Lippert-brand Coachstep Double and Triple Electric Steps. These steps use a bolt to attach the fan gear assembly to the steps. This bolt may fracture allowing the fan gear to disengage from the steps. As a result, the steps may not remain in the expected position and may be unstable.
Consequence: Unstable entry and exit steps increase the risk of injury.
Remedy: Thor will notify owners, and dealers will install a retainer bracket to reinforce the operating mechanism and replace all of the affected bolts, free of charge. The recall began on January 6, 2016. Owners may contact Thor customer service at 1-877-855-2867. Thor's number for this recall is RC000111.
NHTSA campaign record ↗16V571000 · Equipment:Recreational Vehicle/Trailer
Reported: 2016-08-02 (August 2, 2016)
Thor Motor Coach (Thor) is recalling certain model year 2012-2017 Ace, 2013 Citation, 2012-2013 Siesta and 2017 Four Winds and Road Bear Rental motorhomes. The affected vehicles are equipped with shower curtains that may not adequately resist catching fire in the presence of an ignition source. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 302, "Flammability of Interior Materials."
Consequence: A flammable shower curtain may further fuel a fire, increasing the risk of injury.
Remedy: Thor will notify owners, and dealers will replace the shower curtains with curtains made with fire retardant, free of charge. The recall began on September 15, 2016. Owners may contact Thor customer service at 1-877-500-1020. Thor's number for this recall is RC000121.

Emerging complaint spikes
Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.
This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.
No complete months meet the spike thresholds for this selection.
Equal-age model-year comparison
Model-wide cumulative reports during the first three or five calendar years, starting with the model year (age 0). Only fully elapsed windows are compared.
2019: 0 complaints · 2020: 0 complaints
| Model year | Through age 0 | Through age 1 | Through age 2 |
|---|---|---|---|
| 2019 | 0 | 0 | 0 |

Date coverage across each selected cohort
| Year | Incident dates used | Filing date fallbacks | Excluded dates |
|---|---|---|---|
| 2019 | 0 | 0 | 0 |

Incident date is preferred when valid and no later than filing; otherwise filing date is used. Model year approximates age. Equal observation time does not adjust for sales, distance driven or reporting delays. One complaint linked to multiple model years can appear in each cohort.
